The healthcare reform proposed by President Donald Trump to "repeal and replace" ObamaCare, and which was narrowly approved by the Republican-controlled House of Representatives, would leave 23 million people without healthcare coverage over the next decade, the Congressional Budget Office said Wednesday.

The Affordable Care Act (ACA) approved by Obama in 2010, was, despite its failures, his greatest national political achievement which provided health insurance to tens of millions of people and saved as many millions of families who almost fell into bankruptcy because one of their family members were sick.

The vote on the bill was previously scheduled for Thursday but the lack of consensus among conservatives has postponed the process. If the legislation fails, there won’t be another effort to make good on the flagship Republican promise to replace Obama’s Affordable Care Act, Trump said.
